I just picked up a Power Mac G4 1GHz Duel's (MDD) 2002 model, runs like a champ for $0.00. A friend gave me a 1.25GHz Duel 2002 model that won't power up. Here is my question, because I don't know whats wrong with the 1.25GHz can I swap the processor from the 1.25GHz and use it on the 1GHz model to verify if the processor is good, or if the processor is bad on the 1.25GHz could that damage the motherboard on the working 1GHz machine?

Here are the motherboard model numbers if that helps

1GHz Duel = 820-1453-A (2002)

1.25GHz = 820-1474-A (2002)

My ultimate goal is to find out what is wrong with the 1.25GHz machine, (ie) Power Supply, Motherboard or Processor

#1. I did pick-up some Arctic Silver 5 today, however I have never done this before. Arctic's web site really is geared to the pc side of things. Can someone provide me more info using this thermal grease on Power PC chips?

I have not had luck with waking up from sleep mode (in my G3 and G4) and I have absolutely no idea why. I changed my energy saver preferences settings to never sleep and never put the hard drives to sleep, I only use the screen saver. Possibly the hard drive or a PCI/USB/FW peripheral doesn't wake up when it should and then the machine panics? I have no diagnosis or solution to the wake-from-sleep issue, other than to never sleep.

My experience with sleep on these systems are if you have additional PCI card installed that generaly is the reason they fail to go to sleep on therir own, or create a kernal panic when forced to sleep by using the "Sleep Now" drop down menu. Clearly non Apple software can create issues with sleep.

Because this has a virgin system install only, I want to verify everything is top-notch before I install anything else.

See I purchased a new 1.25Ghz DP (MDD) in Spring of 2003, It got damaged in 2007 but I saved everything I could (guts wise, ie: GForce Ti Video Card, Hard Drives) and all the original manuals & discs the only thing I tossed was the box.

I will try the motherboard from the doner machine soon, the one I got the processors from. I noticed that board has a Bluetooth connection (Motherboard # 820-1474-A) does anyone know where I might get the Bluetooth Module for it? It the connection on the board next to the Airport Card.
